因为挑战杯的项目和语音有关，所以在网上找了一些这方面的资料。发现微软的SAPI是一个不错的东西。
下面的程序大部分都是从MSDN中得到的，自己都还没有把SDK的文档看明白:(
有兴趣的可以参见：http://www.microsoft.com/china/community/program/originalarticles/techdoc/Cnspeech.mspx
如果找不到tlbimp命令，可以参见：http://blog.csdn.net/wayne92/archive/2006/04/08/655420.aspx
程序如下：
using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
using System.Threading;
using DotNetSpeech; //这个是要用tlbimp命令生成的。
/**//*PS：发现这样更简单：项目->添加引用->COM 选择Microsoft Speech Object Library，就添加了SpeechLib（和生成的DotNetSpeech一样）*/
